KitchenAid Wall Oven Code F8 E5: exhaust sensing has been lost

What F8 E5 means

On KitchenAid electric wall ovens such as the KODE500ESS, F8 E5 indicates a possible problem with the exhaust fan air temperature sensor or its wiring. The oven loses its reading of exhaust air temperature. You will see the code on the display, and cooking may be interrupted. Because the sensor and wiring are named, a technician tests that sensing circuit before ordering any part.

Common causes of F8 E5

Exhaust fan air temperature sensor reading wrongly
Wiring or connector problem at the sensor

✓ One safe check you can try

1. Press Cancel and wait for the oven to cool. 2. Check that the vent area is clear. 3. Power the oven down at the breaker for a minute and restore it. 4. If F8 E5 returns, call us and leave the oven off.

! Why to stop there

The sensor is part of the oven's heat protection.
Only a test separates a sensor from its wiring.
You approve our written price first, and the work is warranted for 30 days.

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

F8 E5F8 E5 questions

Why is there both an E4 and an E5?

Both name the exhaust fan air temperature sensor and wiring. We test the same circuit for each, then explain what we found and quote before any part is replaced.

Can the oven be used?

Not safely while the code keeps returning. The oven cannot read exhaust air temperature, so it is best left off until the sensor circuit has been tested.

What will you do on site?

Test the sensor and its wiring, explain the result in plain words, and quote the fix in writing. You approve the price before we replace anything.
